[SURBL-Announce] ADVISORY: Please set up local DNS servers for high volume mail servers
by Jeff Chan 23 Apr '04

23 Apr '04

For folks processing more than a a few hundred thousand messages per day, please set set up a local caching name server for any of the RBLs you are using, including SURBLs. This is considered a standard, good practice since it offloads the public name servers. A very popular and fast name server specifically meant for serving up RBLs is rbldnsd: http://www.corpit.ru/mjt/rbldnsd.html SURBL zone files are available in rbldnsd format. Then arrange with the RBLs to get rsync access to their … [View More]

ANNOUNCE: Mail::SpamAsssassin::SpamCopURI 0.13
by Eric Kolve 23 Apr '04

23 Apr '04

I have just released SpamCopURI 0.13. This release adds some basic query caching as well as registrar based lookups against the RBL. Instead of querying for both the 2nd and 3rd level domain we are now only querying for the 2nd OR the 3rd based on the TLD. Let me know if you see any issues with this: false positives, misses that should be hits, etc. We are now caching the query results on a per test basis so multiple URLs to the same to domain should only get checked once per RBL. There … [View More]

[SURBL-Announce] ANNOUNCE: BigEvil.cf and MidEvil.cf are now available in SURBL form as be.surbl.org
by Jeff Chan 22 Apr '04

22 Apr '04

BigEvil.cf and MidEvil.cf are now available in SURBL form as be.surbl.org, for use with SpamCopURI SpamAssassin 2.63 and URIDNSBL SpamAssassin 3.0 plugins. Thanks Chris, Paul and Gary Funck! Here's an excerpt about the new list from the Quick Start section: http://www.surbl.org/ Chris Santerre and Paul Barbeau's BigEvil and MidEvil SpamAssassin rules are now available as an SURBL for use with plugins and programs such as those mentioned above which can extract message body URI domains … [View More]and compare them against name-based RBLs. The name of the list is be.surbl.org, and some sample rules and scores to use it appears below. The well-known and popular BigEvil and MidEvil SA rulesets are used to block messages based on domains that have occurred in spam message body URIs. Using this as an SURBL instead allows you to remove this relatively large ruleset from SA memory and lets DNS cache the data in a zone file instead, querying SURBL hits from DNS as needed. An SA 2.63 rule and score using SpamCopURI (but not the SpamCop data!) looks like this: uri BE_URI_RBL eval:check_spamcop_uri_rbl('be.surbl.org','127.0.0.2') describe BE_URI_RBL URI's domain appears in BigEvil tflags BE_URI_RBL net score BE_URI_RBL 3.0 An SA 3.0 rule and score using URIBL's urirhsbl looks like this: urirhsbl URIBL_BE_SURBL be.surbl.org. A header URIBL_BE_SURBL eval:check_uridnsbl('URIBL_BE_SURBL') describe URIBL_BE_SURBL Contains a URL listed BigEvil tflags URIBL_BE_SURBL net score URIBL_BE_SURBL 3.0 be.surbl.org can be used alone or with other SURBL lists; all that's needed are different rule and score names, as we've shown in the samples. More information about be.surbl.org can be found in the Additional SURBLs section. http://www.surbl.org/additional.html be.surbl.org joins Bill Stearns' sa-blacklist-based ws.surbl.org and my own SpamCop URI-based sc.surbl.org SURBLs. All are described more at the site. Please send me any questions, comments, corrections, updates, etc. Cheers, Jeff C. P.S. We will probably offer a combined list at some point. We're still working out the details of that. Until then it's quite possible to use one or more of the lists simply by using separate SA rules for each one that you want to use, as shown in the Quick Start samples. P.P.S. The sample rules have been updated to mention "SpamCop" only in the descriptions of rules that actually use SpamCop data. -- Jeff Chan mailto:jeffc@surbl.org http://www.surbl.org/ [View Less]

ANNOUNCE: Mail::SpamAsssassin::SpamCopURI 0.11
by Eric Kolve 21 Apr '04

21 Apr '04

I have just released SpamCopURI version 0.11. This fixes a few bugs that had been reported and adds open redirect resolution. This basically takes a URL from say rd.yahoo.com and attempts to resolve the Location header without ever fetching from the potential spammy site. Only the URLs that have hosts that match an address list get redirect resolution. As well, redirect resolution is off by default, but can be enabled in the conf file. I have placed several open redirect sites in the conf … [View More]

SURBL testpoint changed, TXT records shortened
by Jeff Chan 21 Apr '04

21 Apr '04

Here are a couple changes to the SURBL testpoints and TXT records: http://www.surbl.org/news.html 4/20/04: SURBL testpoints "example.com" have been changed to "surbl-org-permanent-test-point.com" to avoid potential spam detection on sample URIs. So the SURBL testpoints are now: Name: test.sc.surbl.org.sc.surbl.org (with ws for sc, etc.) Address: 127.0.0.2 Name: test.surbl.org.sc.surbl.org Address: 127.0.0.2 Name: 2.0.0.127.sc.surbl.org Address: 127.0.0.2 Name: … [View More]

[SURBL-Announce] SURBL web site updated, Letter to Redirectors added
by Jeff Chan 18 Apr '04

18 Apr '04

I've udpated the SURBL web site to use frames and have freshened the content slightly. Please let me know if you spot any broken links, etc. http://www.surbl.org/ Also added "An Open Letter To Operators Of Redirection Sites" in which we try to appeal to redirection sites to deny their services to spam URI domains (e.g., spammers' web sites). Redirection sites may become an increasing problem if we're successful in blocking spams with their sites directly linked. http://www.surbl.org/… [View More]
